CrossGen Entertainment was an independent comic book publisher that eventually became an imprint of Marvel Comics.

Formed by Mark Alessi in 1998, CrossGen published comics until 2003, until they were picked up by Marvel with The Walt Disney Company buying out CrossGen in 2004 for $1 million.

In 2010, then-Marvel editor-in-chief Joe Quesada announced that Disney had given CrossGen over to Marvel (as Disney owned both companies at that time), and that Marvel would be reviving CrossGen as an imprint in 2011.
